Search bar is now hidden. How do I get it back? "Customize" doesn't fix it

I recently reset my Firefox. Previously, the search bar was displayed to the right of the address bar. Now, the search bar is not displayed, and the address bar is wider to take up the extra space. When I go to Customize, the Customize display shows the search bar in its expected location. Moving it to the right or left of its position in the Customize display appears to change its location. But when the Customize display is closed, the search bar disappears again.

I do know that I can use the address bar to search as well. I specifically want a separate search bar which is not overwritten by an address.
